"Unicode Explained is a primary source of information that is essential to an understanding of the "standard." The book puts the specification into the context of real-world application. It throws its net of coverage wide and includes discussionss of the structure of Unicode, character properties, the various encounters, Internet issues, and Unicode characters in programming. Not a book of solutions per se, but a resource essential to finding solutions. Recommended as a library acquisition."
